Contact with the metal frame after the electricity is how to distinguish between static electricity or leakage
Today, friends and friends in the newly renovated new home watching TV, but we only have access to the metal handle and the door when the time will be electricity, and now do not understand is static or socket wire leakage
Static electricity and leakage is easy to distinguish, static electricity is an instant discharge, there is a very low voltage current, once the discharge will be no second electric shock feeling, and leakage will have several electric shock feeling. But now you say this situation is not like static electricity, because the door is installed on the ground has been quietly released, so your situation or because the walls are wet and the possibility of leakage even greater. I suggest you use the power supply line single-phase three-wire system, the total use of leakage protection, it will be more secure.
You touch, was electric, and then touch, if still electricity, that is, leakage; if no longer electricity, is static.
You can try the hand has been on top, to see is not always have Ma Ma feeling, some words is leakage, no is static.
And the power cord is not exposed to static electricity. There may be contact with static electricity may also be leakage.
Static electricity is a kind of Ma electrical feeling. Leakage will be accident. If you can not even worry about a wire to the power of the yellow-green line, it is a protective grounding wire.
